To all whom it may concern:

Be it known that I, CHARLES T. MGEL- vANEY, a citizen of the United States, resid ing at Denison, in the county of Grayson and State ot'` Texas, have invented new and useful Improvements in Headlight Attachments, of which the iollowing is a specifica- My invention pertains to'devices for dislaying numbers or other signals in front of ocomotive headlights; and it has for one of its objects to provide a simple device tor the purpose indicated embodying such a, construction that there is no liability of the numerals or other signals being obstructed or rendered obscure by dirt or other substance.

Another object of the invention is the provision of a device in which no glass or other fragile material is employed., and one ada-ptrV ed to be readily positioned on and attached to locomotive headlights.

Another object is the provision of a device".v

constructed in such manner that .when it is necessary to change the headlight from one locomotive to' another, lates bearing the numerals or other signas may be expeditiously and easily removed and replaced with plates bearing other numerals or signals.

(lther advantageous features peculiar to my invention will be `i'ully understood from the following description and claims when tht` the aceonmanying drawings, forming part of this specilication, in which:

.Figure 1 is a view illustrating a portion of a louomot ive headlight and .my novel display device in proper position thereon. Fig. 2 is an enlarged view of the device removed; the

same being shown partly in horizontal seetion and partly in inverted plan. Fig. 3 a transverse section taken in the plane .indi cated by the line 3 I3 ot' Fig. 2 but showing the device. in. its proper operating position.

Similar letters designate corresponding parts in all oi the views of the drawings, referring to which:

A is a locomotive headlight having the usual circular body d and lens-holding rim or ilangc b; and B is the. body of my novel display device. The said body B is preierably Anado of sl'xeet-.metal in the general form illustrated', and comprises a top Wall cfa back wall d, a 'front Wall e, side walls fiixed to the top, back and front Walls and con verged from the said back wall to the front same are considered in connection with.

wall, and a longitudinal central, vertically disposed partition wall g iixed to the top wall and the front Wall and extending rearwardlyfroni the latter about the proportil nal distance illustrated.

The back Wall d of the body B is provided with a rearwardly extending flange L which describes a part of" al circle and is designed to rest on and be attached to the perimeter of the headlight body (t, while the side walls f tions fixedjto the side Wallsf along the lower Walls oi the openings and upright portions disposed at theopposite ends of the opemngs.

These keeper flanges m are'designed to rer ceive and hold plates (i in which the numerals or other signals l) are out as shown; and by virtue ofthe said plates being arranged in the keeper llanges, it will be apparent that when it is .necessary to change the headlight from one locomotive to another, the plates C may be removed with facility and as readily replaced with other plates provided with the proper numerals or other signals.

'lhe lower side of my novel device or rather the body B thereof is open throughout its area andthe openings l in the side walls of said body are occupied the plates C. By virtue ot this it will he apparent that the in terior oi the body l5 will-be illuminated by the locomotive headlight, and the light will stream. out through the openings l) representing numerals or other signals with the re sult that. the said numerals or signals will be plainly visible at all times and under all conditions of Weather.

With a view oi rendering the numerals or other signals cut in the'plates C more plain and 'prominent 'l contemplate painting or otherwise nnilii'ng the .interior or the body B light in color. .lhis is particularly advan' tageousavhen the partition Wall 5] einployed in the body .l tor then it will be observed that the illumination allorded by the locomotive lu-adlight will enable the said parplates l gathered imm lll@ lo'lcgunm that 'lt will be x,`
